I lost the 2ng BIOS of my RX 580 Nitro?

Hi all, I have a problem. A VERY strange problem. I tell you shortly what happened. I have an Rx 580 Nitro+. This GPU has two BIOS, one "Silence Mode" that is 1340/1411 mhz, the second "Boost Mode" 1411/1440 mhz.

I open MSI Afterburner. I see "1411mhz". I shut down pc, I change the BIOS with the switch. (this is all ok)

Power on pc. Afterburner says 1340mhz. Shut down pc. Change again the BIOS. (this is all ok too)

Power on pc. The windows screen is all bugged, all white and black things appear. Shut down pc. Change BIOS.

Power on pc. All is ok, Afterburner says 1340mhz. Shut down pc. Change BIOS.

Power on pc. All is ok, but Afterburner says again 1340mhz. ***?

Then I try much times to shut down pc and change BIOS, but I can't get anymore the 1411mhz BIOS. How this is possible?

I just did some more tests. If I open the Radeon Wattman and I play a game with gpu at 100%, the maximum gpu core clock is always 1340mhz. But if I open GPU-Z, with one bios it tells me "Gpu clock 1340mhz - Default clock 1340mhz" but with the other bios it tells "Gpu clock 1340mhz - Default clock 1411mhz" but the fact is that I never reach 1411mhz core clock, with both bios it stops at maximum 1340mhz, so not only I can't change bios but I can't get the boost too.
